Be it known that I, GUSTAVE Bouneane, of the city and State of New York, have invented an Improvement in Artificial Manures or Fertilizers; and the following is declared to be a correct description thereof.

'lhisfertilizer is made of blood andlime, mixed together, the albumen being extracted.

The method pursued in the making of this artificial manure is to mix slaked lime with the blood to the extent of about ten per cent-., more or less; then add water, and subject the mass to a low heat to evaporate the water added, or a portion of it; then the coagnlated mass is subjected to pressure, to expel the albumen, as set forth in an application for a patent on improvement in the preparation of albumen of the same date as this application.

The cake or mass of material remaining forms my artificial fertilizer, and it may be dried and ground up, or the water of condensation from the foregoing evaporation (containing ammonia) may be mixed again with the coagnlated mass after the albumen has been removed. 7

My artificial fertilizer, made as iifi)i'6SZi.l(l,lS a new article of manufacture, containing fertilizing proper ties, and utilizing otherwise refuse material.

I claim as my invention-- The fertilizing material, made in the manner substantially as specified.
